In enzymology an aspartate-ammonia ligase (EC 6.3.1.1) is an enzyme that catalyzes the chemical reactionATP + L-aspartate + NH3 AMP + diphosphate + L-asparagineThe 3 substrates of this enzyme are ATP L-aspartate and NH3 whereas its 3 products are AMP diphosphate and L-asparagine.This enzyme belongs to the family of ligases specifically those forming carbon-nitrogen bonds as acid-D-ammonia (or amine) ligases (amide synthases).
